This product has the ability to apply and verify signatures and timestamps.
Here, we will explain the overview of these features.
What is “Applying” a Signature & Timestamp
Applying refers to the act of electronically signing or timestamping a digital document (PDF file in this product).
What is “Verifying” a Signature & Timestamp
Verifying refers to the process of checking the integrity of the signature or timestamp applied to a digital document.
A Digital Signature signature is a technology used to prove that a digital document (PDF file in this product) was created or approved by a specific person or organization, similar to signing a paper document.
In this product, it is possible to apply a digital signature signature with or without a signature timestamp.

To keep a digital Signature signature valid for a long time, you need information to prove that the certificate used for the signature was valid at the time of signing (verification information) and a timestamp.
However, these can only be added in an online environment connected to the Internet.
If you have applied a signature without either or both of the verification information and timestamp to a PDF file that needs to be stored for a long time, it is recommended to perform the following after transitioning to an online environment:
A timestamp is a technology used to provide proof of date and time to a digital document.
By applying a timestamp with a recorded date and time, you can guarantee that the digital document existed at that time and that the document has not been tampered with after the application.
This product can apply several types of timestamps, but all require an online environment to apply.
